CLUTCH.

Original application filed May 1, 1909,

To all whom it may concern: v

Be it known that we, \VILLIAM S. Hover and CHARLES B. STEBBINS, citizens of-the United States, residing at the city of Three Rivers, county of St. Joseph, Stateot' Michigan, haveinvented certain new and useful Improvements in Clutches, of which the following is a specification.

- This invention relates to improvements in Our improved clutch is especially designed by us for use on motor. cars such as are illustrated in our application for Letters Patent, filed May 1, 0t-'), Serial No. 493,373, of which application this is a division, although it is The main objects of this invention are to and effective, and at the same time one which is comparatively simple and economical in structure and compaee in its arrangement of parts. i

Further objects, and'objects relating to structural details, will definitely appear from the detailed descriptionto follow.

lVe accomplish the objects of our 1DVG1P tion by the devices and means described in the following specification.

The structure described constitutes one effective embodiment of our invention. Other embodiments would be readily devised by those skilled in'the art.

The invention clearly defined ed out in the claims.

A structure constitutingan efi eetive and preferred embodiment of the features of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

l igurel is a side elevation of a car wheel and point- Fig.2 is; an enlarged detail vertical section talc-en on aline corresponding to line 2--2 of Fig. 1. Fig. 3 is atransverse section taken on a line corresponding. to broken line 3--3 of Fig. 2., 1

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at theends of the section lines;

Referring to the drawing, 1 represents the car wheel in connection with which we have Specification of Letters Patent. Patented NOV. 23, 1909.

illustrated our improved clutch. This may,

it is obvious, be any desired member which I it is desired to drive through the clutch.

2 represents the drive chain and 3 a portion of the car frame.

'lhe conical driven -clutch member 4 is connected to the wheel 1, it being preferably formed,integrally with the hub 5 ot' the wheel as is illustrated.- The wheel is in the structure illustrated secured upon-the hub 5 by means of the ren'iovable flange "G and the bolts 7. The axle 8 is shouldered at 9 to en 'age the-innerend of the hub and the wheel is retained on the axle by means of the nut 10. The driving wheel or sprocltet 11 is provided with an offset hub 12 which projects into the driven member 4. A bush lug-13 is preferably provided-for thehub of the driving wheel 11, the bushing having a flange 14 at. its inner end which bears againstthe end of the hub 5 of the driven member 4. The axle 8 is provided with a flange 15 between which and the end of the hub 13 of the driving wheel we preferably arrange a bearing washer 16. This rovides effective bearings for the parts an a convenient means for assembling and securing them in place.

The driving clutch member 17 is adjust-v ably mounted one hub 13 of thedriving wheel 11., it being'slidably connected to the driving wheel 11-by means of the driving pins 18. The's pins are threaded into-- the driving clutch member 17 and slidably arranged through holes 19 provided therefor in the driving wheel 11. On these pinsare springs'QO which retract or draw the d'riving clutch member out of its' engaging or driving position. The tension of these springs is regulated by the nuts 21 threaded upon the pins. The driving member is thrown into its engaging position by meansof the actuating. levers 22 which are mount- 1 ed on suitable pivots 23, carried by the driving wheel 11, so that their inner ends engage a. ringelikmmember 2 1 carried by the driving clutch member 17, the member 24 being -.a1.-ranged on the hub of the' driving clutch member as clearly appears from 2.. This member 24 i; prcterablythreaded upon the hub so that it may beadjusted thereon. The member 24. is secured in its adjusted position by means o't'lthe loekmg pm 25 carried by the driving wheel 11, the

pin being arranged to .engage'suitableholes 26 provided therefor in the member 24.

The levers 22 are actuated by means of the conical cam 27 which .is slidably mounted upon theaxle S to engage the ends of the levers as clearly appears in Fig. 3. When this cam is shifted inwardly the outer ends of the levers. are raised thus throwing their inner ends a 'ainst the member 24, forcing the driving clutch member into engagement with the driven clutch member. The clutch actuating cam 27 is shifted by means of the forked lever 28 which is provided with suitable: cam-engaging lugs 29; The cam is preferably provided withja'gro'ove 30 in whichthe ends of the, levers 22 engage to.

' retain the clutch in engagement. The drivjwith friction members 31.

By this arrangement of the parts we seing; clutch member is preferably provided cure'a clutch mechanism which is very powferful, and is at the same time compact so claiming the same not only inthe specific form illustrated but also broadly within the scope of the appended claims.
